“…The survey showed a similar frequency of occupational sensitization (~50%) to locusts as that observed in previous studies. [3][4][5][6] Although the allergic disorders included atopic dermatitis, allergic rhinitis and asthma, most male patients with allergies exhibited difficulty breathing, as in asthma, while female patients showed a prevalence of atopic dermatitis. However, men and women do not have different divisions of labour, they did the similar work and in a common exposure environment, therefore these differences may be caused by the gender itself.…”

“…3 Orthopteran insects, including grasshoppers, locusts, and crickets, are important occupational hazards because of the severe symptoms caused by insect allergens. [4][5][6] Locusts are not only one of the world's most destructive agricultural pests but also model systems in many laboratories for studying behaviour, physiology, neuroscience, and phenotypic plasticity. 7,8 Several cases of occupational allergies have been described as allergies to the migratory locust, American locusts and grasshoppers, with symptoms of asthma, dermatitis, rhinitis and even shock.…”

Background: Occupational exposure to locusts induces a high prevalence of allergic sensitization. However, knowledge on occupational locust allergens remains unclear.Objective: This study aimed to identify the allergens from locusts causing occupational allergies. Methods: We conducted a survey of 57 persons exposed to locusts using questionnaires and immunological tests for occupational allergies in long-term locust laboratories. The major allergen was identified by immunoblotting and analysed by mass spectrometry. The allergenicity of the allergen was assessed by sIgE detection, immunoblotting and ELISA inhibition assays. Results: The survey indicated that the frequency of locust occupational allergies was 40.4% among subjects exposed to locust. The symptoms in most males were allergic rhinitis, while females showed higher prevalence of atopic dermatitis. Occupational exposure increased the allergy risk. The recombinant hexamerin-2 protein possesses high allergenicity in the allergic exposure group. Hexamerin-2 protein can inhibit IgE reactivity with locust protein extracts by approximately 60%. The potential for cross-reactivity with cockroaches was indicated by sequence alignment of hexamerin-2 protein and allergens of cockroaches. Conclusion:The hexamerin-2 protein of locusts as an important allergen was identified. Therefore, occupational exposure is an important risk factor for locust allergy.

“…Insects are a major source of allergens for humans, and insect asthma and allergy symptoms can be induced by bites, stings, inhalation, and ingestion [ 78 ]. Exposure to insect particles can occur in indoor and outdoor environments during daily life in non-occupational settings, as well as in occupational settings [ 79 ]. There is a large regional difference in the rate of sensitization to insect allergens, which might reflect differences in the numbers and types of insects dominant in the environment [ 78 ].…”

Insects are, by far, the most common animals on our planet. The ubiquity and plethora of ecological niches occupied by insects, along with the strict and sometimes forced coexistence between insects and humans, make insects a target of public health interest. This article reports the negative aspects historically linked to insects as pests and vectors of diseases, and describes their potential as bioindicators of environmental pollution, and their use as food and feed. Both negative and positive impacts of insects on human and animal health need to be addressed by public health professionals who should aim to strike a balance within the wide range of sometimes conflicting goals in insect management, such as regulating their production, exploiting their potential, protecting their health and limiting their negative impact on animals and humans. This requires increased insect knowledge and strategies to preserve human health and welfare. The aim of this paper is to provide an overview of traditional and emerging topics bridging insects and public health to highlight the need for professionals, to address these topics during their work. The present and future role and activities of public health authorities regarding insects are analyzed.

“…The following occupations have been connected to respiratory insect allergies: anglers and fishers, laboratory workers, employees of aquaculture companies, farmers, bakers, sericulture workers and pet shop workers [6,7]. Occupational insect allergies are usually provoked by the wings, legs, setae, scales or feces of the insect, and although occupational insect allergies are often respiratory, they can be cutaneous as well [8].…”

A significant part of adult-onset asthma is caused by occupational exposure to both high- and low-molecular-mass agents. Insects are occasionally described to cause occupational allergy in professions including anglers and fishers, laboratory workers, employees of aquaculture companies, farmers, bakers, sericulture workers and pet shop workers. Occupational insect allergies are often respiratory, causing asthma or rhinoconjunctivitis, but can be cutaneous as well. The European Union recently approved three insect species for human consumption, enabling an industry to develop where more employees could be exposed to insect products. This review overviews knowledge on occupational insect allergy risks and the tools used to diagnose employees. Despite the limited availability of commercial occupational insect allergy diagnostics, 60.9% of 164 included reports used skin prick tests and 63.4% of reports used specific IgE tests. In 21.9% of reports, a more elaborate diagnosis of occupational asthma was made by specific inhalation challenges or peak expiratory flow measurements at the workplace. In some work environments, 57% of employees were sensitized, and no less than 60% of employees reported work-related symptoms. Further development and optimization of specific diagnostics, together with strong primary prevention, may be vital to the health conditions of workers in the developing insect industry.
